Steps to Reproduce

Run Fiddle: http://zkfiddle.org/sample/3in3jc4/1-collapsed-navbar-with-selected-sub-menuitem-bug
Hover your cursor over the "BA" or "BB" entries and see the menu entries jumping to their correct positions.

Actual Result

Initial rendering of a navbar menu structure is incorrect having a pre-selected sub menuitem.
It does not match the "collapsed style"

Expected Result

no initial animation, hidden <navitem>s

Debug Info

in collapsed mode the <navitem>s are only visible when hovering the parent <nav> element
<child>navitems don't affect the height/width of the surrounding <navbar>

Workaround

<script><![CDATA[
/*workaround for ZK-3609*/
zk.afterLoad('zkmax.nav', function() {
	var xNav = {};
	zk.override(zkmax.nav.Nav.prototype, xNav, {
		open : function() {
			//don't open the top most <nav> widgets when collapsed
			if(!this.getNavbar().isCollapsed() || !this.isTopmost()) {
				xNav.open.apply(this, arguments);
			}
		}
	});//zk.override
});//zk.afterLoad
]]></script>
